Électricité Sécurité

Look for the works you cannot see once plasterboard closes: cable routes and sizes, protective devices, earthing and bonding, and the labelling of the distribution board. A quote that lists tests, measurements and the report you receive is more valuable than one counting outlets alone, because compliance is what makes the installation insurable and safe.

Ask how existing circuits are reused or replaced, how walls and ceilings are made good after chasing, and what happens to the supply while works proceed. For alarms, cameras, intercoms and automation, confirm who owns the accounts and configuration, how the system is documented and what maintenance or updates it needs afterwards. Handover should include a walkthrough of how to operate everything.

Electrical work is checked against standards, so the value of a quote lies in what is verified rather than in the visible sockets. On older installations, the questions are the state of the distribution board, earthing and bonding, the condition of cable insulation and whether circuits are adequately protected. Adding a heat pump, charging point or induction hob changes the load and often needs its own dedicated circuit.

Security and comfort systems, alarms, cameras, intercoms, access control and home automation, depend on cabling routes and network coverage decided during the works. Ask the installer to confirm what will be tested, which certificates or reports you receive, and how the system is handed over so you can operate and maintain it yourself.

This category brings together two complementary trades. The electrical side includes wiring, installation by an electrician, lighting, home automation, intercoms, aerials and satellite dishes, plus equipment linked to electric mobility and energy: EV charging stations, photovoltaic panels, home batteries. The security side covers fire safety, fire doors and reinforced security doors, alarm systems, video surveillance and safes.

Photovoltaics, EV charging stations and home batteries also have dedicated pages on vert.lu with more detail on sizing and technology-specific aids; this page covers the whole electricity and security category across the board.

Any work on an existing electrical installation — adding a circuit, replacing the fuse board, extending wiring — must be entrusted to a qualified electrician. A modified or new electrical installation is subject to a conformity check by an approved body before it is put into service; this check is a condition for the safe use of the home, not a mere formality.

Fire safety systems, fire doors and the smoke detectors required in dwellings are likewise installed by a professional, since their effectiveness depends on correct positioning and connection. An alarm or video surveillance system may sometimes be installed by a homeowner for simple, wireless equipment, but integrating it into an existing installation or into the home's automation system is more reliable with an installer.

For an electrical project, the company starts by surveying the existing installation, identifying available power and future needs, then provides a quote specifying the circuits to create or modify, the equipment used and the planned electrical protections. The work itself often takes a day to a few days for a partial upgrade, longer for a complete overhaul of the fuse board and wiring of a home.

For a security system, the site visit defines the sensitive points to cover (access points, openings, risk areas) and helps choose between a wired or wireless solution. Installation is followed by commissioning with equipment testing and, often, an explanation of how the system works for the owner.

In both cases, keep the fuse board and relevant areas accessible, and ask the company for a document summarising the circuits or areas covered, for your records and any future work.

For electrical work, the number of points to create or modify, the complexity of the existing wiring, the age of the installation and the level of home automation wanted strongly affect the quote. A full fuse board replacement requires far more work than simply adding sockets.

For security, the number of cameras or detectors, the surface area to cover, the choice between wired and wireless, and adding remote monitoring with a subscription are the main factors. A custom fire or security door costs more than a standard model fitted to a common opening.

Ask for a quote that separates equipment supply, installation labour, connection and, where relevant, commissioning or a remote-monitoring subscription.

Klimabonus Wunnen, which replaced the former PRIMe House programme in 2022, supports certain energy-related equipment in this category, in particular photovoltaics, home batteries and EV charging stations: consult our dedicated pages and the official terms for precise conditions. Purely electrical renovation work or security systems, however, do not fall under this scheme.

For any new or modified electrical installation, keep the conformity certificate issued after the check: it is requested when the network operator commissions the installation and is useful should you sell the property.

Check that the electrician or installer holds a business permit for the relevant activity and professional liability insurance; our company profiles list the public information available. For a security system, ask whether the company also handles maintenance and after-sales service, a point often overlooked at the time of signing.

Compare quotes on an identical basis: brand and model of equipment, number of points or areas covered, guarantees, and whether commissioning and conformity steps are included.
